Abstract

The invention relates to a nine-motion-degree robot mechanism. The nine-motion-degree robot comprises a big three-dimensional rotating arm mechanism, a small three-dimensional rotating arm mechanism and a three-dimensional rotating platform mechanism, which are serially connected to each other, wherein three linear drivers are in parallel connection and are used for driving each joint, thereby realizing a big operating space and a flexible track output of the mechanism. The nine-motion-degree robot mechanism is simple and compact in structure and is excellent in error compensation. By mounting end effectors with various different functions on a three-dimensional rotating platform, the nine-motion-degree robot mechanism can be applied to the production of industries, such as carrying, stacking, assembling, cutting, and the like, and also can be applied to the fields of engineering machinery, such as excavators, and bionic mechanisms, such as bionic arms, bionic legs and the like.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a robot mechanism with nine degrees of activity. Background technique [0002] Robots are widely used in welding, handling, palletizing, assembly, cutting and other operations in industrial production. Among them, the robots that have been better applied are basically articulated robots, mostly with 6 axes, and the end tools are sent to different spatial positions through joint actions of 1, 2, and 3 axes, supplemented by 4, 5, and 6 axes. The linkage to meet the different requirements of the tool attitude. The mechanical structure of the robot body mainly has two forms: a parallelogram structure and a side-mounted structure, and it has been widely used because of its large working space and relatively flexible movements. However, due to the limitations of its own structure, this kind of traditional open-chain series robot mechanism requires the drive motor to be installed at t...
